Abstract
A forceps includes a housing having a shaft. An end effector assembly operatively connects to a distal end of the shaft and includes a pair of first and second jaw members. One or both of the first and second jaw members is movable relative to the other jaw member from a clamping position to an open position. A resilient member operably couples to the first and second jaw members. The resilient member is configured to bias the first and second jaw members in the clamping position and provide a closure force on tissue disposed therebetween.

(canceled)
A surgical instrument, comprising:
- a shaft having a proximal end and a distal end and defining a longitudinal axis therethrough;
- an end effector assembly operably coupled to the distal end of the shaft and including a first jaw member and a second jaw member, at least one of the first or second jaw members movable relative to the other jaw member;
- a support structure operably coupled to the shaft and defining an aperture therethrough;
- a drive rod configured to translate along the longitudinal axis and through the aperture, the drive rod operably coupled to at least one of the first or second jaw members;
- and
- a resilient member disposed between the support structure and a proximal end of at least one of the first or second jaw members.
An electrosurgical system, comprising:
- an electrosurgical generator;
- and
- an surgical instrument configured to couple with the electrosurgical generator, the surgical instrument comprising:
- a shaft having a proximal end and a distal end and defining a longitudinal axis therethrough;
- an end effector assembly operably coupled to the distal end of the shaft and including a first jaw member and a second jaw member, at least one of the first or second jaw members movable relative to the other jaw member;
- a support structure operably coupled to the shaft and defining an aperture therethrough;
- a drive rod configured to translate along the longitudinal axis and through the aperture, the drive rod operably coupled to at least one of the first or second jaw members;
- and
- a resilient member disposed between the support structure and a proximal end of at least one of the first or second jaw members.
